Kentucky head coach John Calipari has every member of his team practicing with a body monitoring device that measures their exertion rate, sport zones, caloric expenditure and heart rate.

"Everybody perceives his exertion level differently," writes Calipari on his blog. "Some feel they are working extremely hard and they’re not, and others perceive that they’re not working very hard when they really are. My hope is to get everybody in that second category. I want them to realize what their exertion level is in games compared to what it is in practice, and this device helps us do that."
